ABSTRACTBackground Prognostic nutritional index has been found to be related to the clinical outcomes of patients with cancer. However, its role in myelodysplastic syndromes (MDS) patients is unclear. We aimed to assess the value of nutritional status in predicting the prognosis of MDS patients.Methods Totally 121 MDS patients were analyzed retrospectively. The prognostic nutritional index (PNI) was used to assess nutritional status of the patients. The bio-informatics tool X-tile was used to define the threshold, and accordingly patients were divided into PNIlow and PNIhigh groups, the characteristics were compared between two groups.Results The PNIhigh was associated with better OS (Overall Survival) than PNIlow in MDS patients (Median OS, 28.03 months versus 19.63 months, P = 0.0205). But there were no statistical differences in PFS (Progression-Free-Survival) between the two groups (P = 0.9373). The univariable and multivariable COX proportional hazard analysis adjusted for age, gender, platelet count, HB level and IPSS-R scores, and the results showed that PNI is a useful index in the evaluation of the OS of MDS (HR 0.588, 95%CI 0.374–0.926, P = 0.024).Conclusion PNI would be a simple and immediately available tool for predicting the prognosis of MDS.

To explore the prognostic value of red blood cell distribution width (RDW) in newly diagnosed aplastic anemia (AA) patients treated with cyclosporine A (CsA) plus androgen or CsA alone. We retrospectively analyzed the clinical outcome of 220 patients with AA. According to the baseline level of RDW before treatment, the patients were divided into the high-RDW group (RDW ≥ 15%) and the normal-RDW group (RDW < 15%). The median RDW of non-severe AA (NSAA) and severe AA (SAA) patients was 15.65% and 15.35%, respectively; this were significantly higher than that of very severe AA (VSAA) patients (13.35%). With median follow-up being 46 months, AA patients in the high-RDW group showed better 5-year OS and PFS than the normal-RDW group (93%: 75.3%; 74.3%: 61%). There was a higher ORR in the high-RDW group than the normal-RDW group (68.7%: 52.3%). The ORR of NSAA patients in the high-RDW group was better than that in the normal RDW group (75.8%: 60%). The 5-year OS of SAA/VSAA patients in the high-RDW group was significantly higher than the normal-RDW group (81.8%: 50.8%). This is the first documentation on the prognostic value of RDW in AA patients receiving CsA treatment with long-term follow-up, which had shown that high RDW at diagnosis was a better prognostic factor.

An effective salvage regimen for the reinduction of remission is lacking for refractory or relapsed primary central nervous system lymphoma (r/r PCNSL). This study aimed to evaluate the efficacy and safety of cytarabine plus temozolomide in treating r/r PCNSL and to explore the associated prognostic factors. A single-center retrospective cohort study was conducted to assess the efficacy and safety of cytarabine and temozolomide (AT) in r/r PCNSL patients. KIR and HLA genotyping was performed on peripheral blood samples. Thirty PCNSL patients receiving an AT regimen (cytarabine 3 g/m2 for 2 days combined with temozolomide 150 mg/m2 for 5 days) in our institution were analyzed. The median age was 65 years (range 25–79 years). A total of 43.4% of patients (13/30) achieved an overall response within a median follow-up of 16 months (95% confidence interval [CI]: 11–23 months). The median PFS and OS of the cohort were 1.5 months (95% CI: 1–4 months) and 19.5 months (95% CI: 11 months to not calculable), respectively. Patients harboring KIR3DL1/HLA-B genotypes predicting low affinity had a higher response rate (p = 0.042) and longer median PFS (3 months) than those with KIR3DL1/HLA-B genotypes predicting high affinity (1 month) (p = 0.0047). Cox regression analysis indicated that KIR/HLA-B genotypes were independently associated with PFS (p = 0.043). However, KIR/HLA-B genotypes had no impact on the OS of the cohort. The toxicity of AT treatment was mild and manageable. The AT regimen was well tolerated, and patients with specific KIR-HLA genotypes may benefit from this regimen. [ABSTRACT FROM AUTHOR]

Acute myeloid leukemia (AML) with t(8;21) is generally associated with a favorable clinical course. Loss of sex chromosome (LOS) are frequently observed in t (8;21) AML, but the prognostic value of LOS remains uncertain. A total of 73 patients with AML with t(8;21) were studied and divided into t(8;21) with LOS group (n = 36) and t(8;21) alone group (n = 37). The patients with t(8;21) AML with ACAs other than LOS were excluded. The clinical characteristics of these two groups were compared, and the prognostic value of LOS was evaluated based on disease-free survival (DFS) and overall survival (OS). The clinical characteristics (except for gender) were found to have no significant difference between these two groups, and the male patients tended to account for a larger proportion in the former group (P =.001). The OS of the t(8;21) AML with LOS group was significantly longer than that of the t(8;21) AML alone group (P =.005). While not obvious, the patients with LOS seemed to have longer DFS (P =.061). The multivariable analysis also showed LOS to be an independent favorable prognostic factor of t(8;21) AML (P =.022). Our results suggested that LOS could be associated with a favorable prognosis in t(8;21) AML patients without other ACAs, and for this subtype of AML, longer DFS and a satisfactory and stable survival can be achieved with high-dose cytarabine (HDAC) consolidation treatment.

Anaplastic lymphoma kinase negative anaplastic large cell lymphoma (ALK- ALCL) is a definite entity in the WHO 2016 Classification that represents 2–3% of non-Hodgkin lymphoma (NHL) and 12% of T-cell NHL cases. ALK- ALCL lacks ALK protein expression, but expresses CD30 and has morphologic features similar to ALK positive anaplastic large cell lymphoma (ALK+ ALCL). Some studies indicate that ALK- ALCL and ALK+ ALCL possess different molecular and genetic characteristics. Besides, ALK- ALCL is worse than ALK+ ALCL in terms of treatment outcome, prognosis, and long-term survival. This review is aimed at summarizing information about ALK- ALCL, especially with respect to the treatment and prognosis. [ABSTRACT FROM AUTHOR]

Background: Adult secondary hemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening syndrome characterized by excessive activation of mononuclear-phagocytic system resulting in hyperinflammatory response. To date, the factors influencing early death of HLH are still not fully elucidated. Patients and Methods: We did a retrospective study of 171 adult patients with newly diagnosed HLH at our institution from January 2012 to April 2018. All patients' clinical features, laboratory findings, treatments and prognosis were reviewed. Results: The median age was 49 years (range, 18–88 years), and 110 (64.3%) were male. The major underlying trigger of HLH was malignancy (88/171, 51.5%), especially non-Hodgkin lymphoma. In a multivariate analysis, age ≥54 years (P = 0.002), platelet ≤39.5 × 109/L (P = 0.028), activated partial thromboplastin time (APTT) ≥54 sec (P = 0.048), triglyceride ≥3.23 mmol/L (P < 0.001), lactate dehydrogenase (LDH) ≥1300 U/L (P = 0.012) and malignancy (P = 0.001) were significantly associated with early death in HLH. Then, patients were classified into four groups according to the number of risk factors at the time of diagnosis: low risk (zero, one or two risk factors), low intermediate risk (three risk factors), high intermediate risk (four risk factors) and high risk (at least five risk factors), with the 30-day overall survival (OS) of 92.4%, 58.8%, 30.0% and 4.8%, respectively (P < 0.001). Conclusions: Patients with old age, thrombocytopenia, prolonged APTT, hypertriglyceridemia, elevated LDH and malignancy had inferior survival. It is important to identify those patients at risk of early death, which may guide treatment and reduce mortality. [ABSTRACT FROM AUTHOR]
